Site history

The City of Ephrata began operating the Ephrata Landfill around 1942 and owned and managed it until 1974. Grant County has managed the landfill since 1974. The landfill was an open dump before 1962. About 2,000 drums of industrial waste were buried in August 1975. Waste was put into an unlined cell until 2005.

The Environmental Protection Agency added the landfill to the list of potential hazardous sites in 1979. Ecology completed a Phase I site investigation in 1987, and groundwater sampling began in 1988. In 1990, contaminants, including metals, solvents, and other chemicals, were found in groundwater.

Since 2007, the site has had ongoing investigation into the extent of contamination, and the parties responsible have completed several interim cleanup actions. Waste is no longer accepted in the old landfill cell.
